me too, most post by izso :top:, all really informative.ahh cant wait for the piping info... really interesting on that 1 i felt.
Erm.. this is an extractor topic, not exhaust topic. Not quite the same thing? Related but not related. LOLHow can the valve over lapping coverage missing in an exhaust related topic?
You're getting into specifics and that's more advanced than what Drex has explained. Have a read here and see if it answers your questions :hmm..good read.
but i've been reading around and yet still unable to get a concrete answer to it.
if 4 - 1 provides power at higher rpm and 4-2-1 at lower...
how about...equal lengths and unequal length headers? as such for example; scoobies have performance setup for both equal and unequal lengthed extractors....
dispite the fact uneqal length gives you a much clear growling,but....if aftermarket high performance company makes both of them surely there's a difference in it's output...anyone has a concrete answer to this?
Thanks a bunch

Apparently this guy got inspiration from someone in ZTH! Doesn't really talk about how he did the calculation though but is still a pretty good read.
